Delta Air Lines is the latest company to fall into the path of President Donald Trump's Twitter account.

Trump cited a Delta computer failure, which caused delays and more than 300 flight cancellations, as a primary source of trouble at airports over the weekend.

Trump on Friday signed an executive order that banned inbound travel from seven Muslim-majority countries.

The order halted refugee arrivals into the US for 120 days, and it barred citizens of Iraq, Iran, Sudan, Libya, Somalia, Syria, and Yemen for 90 days. It also indefinitely bars Syrian refugees from entering the US.

The quick rollout of the order stranded some passengers from the seven countries in airports throughout the US and caused confusion among authorities over how the ban should be enforced.

"Big problems at airports were caused by Delta computer outage, protesters and the tears of Senator Schumer," Trump tweeted, also referring to Sen. Chuck Schumer, who teared up while speaking out against the ban at a protest in New York.

"I want to apologize to all of our customers who have been impacted by this frustrating situation," Delta CEO Ed Bastian said in a press release early Monday. "This type of disruption is not acceptable to the Delta family, which prides itself on reliability and customer service. I also want to thank our employees who are working tirelessly to accommodate our customers."

Delta also issued a statement on Saturday saying it would "make every effort" to assist customers affected by Trump's executive order.

"Delta will make every effort to contact impacted customers with flexible rebooking options including refunds," the statement said.

Delta stock was slightly lower in trading after the tweet. As of 9:30 a.m. ET, shares were down roughly 1.6% at $48.90.
